AI solves a 50 year biological problem of protein folding!
Han from WrySci HX goes through the recent scientific breakthrough by AlphaFold from DeepMind. The ability to accurately predict a protein structure just based on an amino acid sequence will be a complete game changer. More below ↓↓↓

MHRA will only become fully independent on 1 January 2021, following Brexit, but U.K. regulations allow it to grant authorizations on an emergency basis. The United Kingdom has bought 40 million doses of the Pfizer/BioNTech vaccine—enough for 20 million people—and health secretary Matt Hancock today announced the first 800,000 doses will be available next week. The rollout will prioritize health workers as well as the elderly and other vulnerable populations, but the Joint Committee on Vaccination and Immunisation has yet to offer its final guidance on the exact priorities.
Russia on 11 August allowed its COVID-19 vaccine, developed by the Gamaleya Research Institute of Epidemiology and Microbiology, to be used on certain groups of people, and China has granted emergency use authorizations (EUAs) for several vaccines and has already vaccinated hundreds of thousands of people with them. A few other countries, including the United Arab Emirates and Bahrain, have issued an EUA for one of the Chinese vaccines, produced by Sinopharm.
The Pfizer vaccine, whose key ingredient is messenger RNA that encodes the spike protein of the pandemic coronavirus, was found to have 95% efficacy, a clinical trial measurement of effectiveness, in a phase III trial in 43,000 people. But it presents logistical challenges for a widescale and rapid rollout, as it requires storage at −70°C. The lesser demands of other vaccines—including a candidate developed by the University of Oxford and AstraZeneca—mean they will likely still play an important role in providing vaccinations for the whole U.K. population—and for global coverage, according to Michael Head, a global health researcher at the University of Southampton, “but, for now, this is wonderful news to wake up to.”
So AI is now designing robots. 😃
At first the designs were nonsense, but the (human) engineers trained it on animals and arthropods.
Stanford University engineers have developed an airborne method for imaging underwater objects by combining light and sound to break through the seemingly impassable barrier at the interface of air and water.
The researchers envision their hybrid optical-acoustic system one day being used to conduct drone-based biological marine surveys from the air, carry out large-scale aerial searches of sunken ships and planes, and map the ocean depths with a similar speed and level of detail as Earth’s landscapes. Their “Photoacoustic Airborne Sonar System” is detailed in a recent study published in the journal IEEE Access.
“Airborne and spaceborne radar and laser-based, or LIDAR, systems have been able to map Earth’s landscapes for decades. Radar signals are even able to penetrate cloud coverage and canopy coverage. However, seawater is much too absorptive for imaging into the water,” said study leader Amin Arbabian, an associate professor of electrical engineering in Stanford’s School of Engineering. “Our goal is to develop a more robust system which can image even through murky water.”
SpaceX Starship will fly nine miles into the air later this week according to Elon Musk, who says it has a one in three chance of landing safely.
The massive Starship two-stage-to-orbit heavy lift vehicle has been in development since 2012 and is designed to bring the cost of launch down by being reusable.
Musk says the first ‘high-altitude test’ of the rocket will see it fly nine miles up above the Boca Chica facility in Texas at some point this week — possibly tomorrow.
Yummy?
Eat Just Inc., a maker of meat and egg substitutes, has been approved to sell its laboratory-created chicken in Singapore, which becomes the first government to allow the sale of cultured meat.
You can’t see it. You can’t feel it. But the substance scientists refer to as dark matter could account for five times as much “stuff” in the universe as the regular matter that forms everything from trees, trains and the air you breathe, to stars, planets and interstellar dust clouds.
Though scientists see the signature of dark matter indirectly in the way large objects orbit one another—particularly how stars swirl around the centers of spiral galaxies—no one knows yet what comprises this substance. One of the candidates is a Z’ boson, a fundamental particle that has been theorized to exist but never detected.
A new proposed experiment could help scientists determine whether Z’ bosons are real, in that way identifying a possible candidate for dark matter. To accomplish this task, researchers from the National Institute of Standards and Technology (NIST), the University of Groningen in the Netherlands, the Canadian particle accelerator center TRIUMF and other collaborators are working to make the most accurate measurements to date of a nuclear property that is extremely difficult to measure, called nuclear spin-dependent parity violation (NSD-PV).
UNC School of Medicine researchers identified the amino acid responsible for the trip.
Earlier in the year, many funders agreed to extend deadlines for research projects halted or delayed by the pandemic — but fewer offered extra funding to cover this period. Worryingly, most of the funders we approached still have no concrete plans to provide such additional financial support to postdocs. Many postdocs are not eligible for the government salary subsidies, or furlough schemes, that have been made available to many workers during the pandemic. Expanding access to such schemes is arguably the one intervention that could do the most to ease pressures at this time.
Most funders have no plans to provide postdoctoral researchers with additional pandemic funding. Society will pay a high price if this neglect continues.
